Preconception Screening tests are usually done by your OB or primary care physician during your first prenatal visit.
Ideally these tests are done before your referral for fertility evaluation and treatment:
- Prenatal or Obstetrics panel tests for rubella immunity, blood type, hepatitis B antigen, RPR for syphilis, blood count (CBC), and Pap smear.
- Infectious diseases screening for HIV 1 and 2 plus O, hepatitis C antibody, varicella immunity, CMV (cytomegalovirus IgG and IgM), gonorrhea, and chlamydia.
- Genetic carrier screening. The American College of Obstetricians and Gynecologists (ACOG) March 2017 Committee Opinion #691 now recommends that information about genetic carrier screening should be provided to every pregnant women and ideally performed before pregnancy. Carrier screening can include testing for genetic conditions such as cystic fibrosis, sickle cell disease, thalassemia, spinal muscular atrophy, Tay Sachs, and Fragile X, to name a few. Screening is most often done for recessive genetic diseases for which the carrier (parent) is unaffected. If both parents are carriers for a mutation in the same gene they have a 25% risk of having an affected child.
